GUN SIGHT Filed May 22, 1937 INVENTOR. CRAWFORD C LOOM/S.

: A TTORNEY Patented Oct. 17, 1939 UNITED STATES PATENT OFFICE GUN SIGHT Crawford 0. Loomis, Ilion, N. Y., assignor to Remington Arms Company, Inc., a corporation of Delaware Application May 22, 1937, Serial No. 144,139

3 Claims.

This invention relates to firearms sights, particularly sights of the so-called hooded type, and contemplates novel means for removably securing a hood to a sight of this character.

In the drawing:

Fig. 1 is a front elevation of sight embodying one form of the invention.

Fig. 2 is a section substantially on the line 2-2 of Fig. 1.

Fig. 3 is a fragmentary front elevation of the supporting member and sight base, the hood being removed.

Fig. 4 is a fragmentary rear elevation of the supporting member and sight base, the hood being removed.

Fig. 5 is an inverted plan view of the hood.

The sight selected for the purpose of illustration comprises a supporting member which is secured to a firearm by means of a ring Ill adapted to encircle the firearm barrel. Integral with the ringlgi A, ,3 d a sight base l2 comprisinga recess adapted to receive the V-block base of a sight member l3 provided with any suitable sight surface l4. The sight base l2 comprises vertically disposed parallel sides and vertical front and rear ends identified by numerals l5 and I 6, respectively.

The hood, which is a cylindrical member identified generally by numeral l1, comprises a rectangular aperture l8 of such width and length as to receive the sight base l2. The forward end of hood I! is exteriorly threaded and receives an interiorly threaded and exteriorly knurled collar IS, the inner end of which is beveled or curved as shown at 20. The collar I!) may be advanced upon the hood H to overlap the end portion of aperture l8.

In the rear end I6 of the sight base I2 is formed a groove 2| of the same curvature as the hood and of a width slightly greater than the thickness of the stock 'of the hood. In the front end [5 of the sight base is formed an arcuate groove 22 adapted to receive the beveled end 20 of collar I9. In assembly, the collar I9 is retracted to clear the aperture l8 and the hood is inserted over the sight member and base and drawn forwardly until the part 23 of the hood adjacent the rearward margin of the aperture I8 enters the groove 2|; the collar I9 is thereupon advanced by rotation upon the tube I! to enter the arcuate groove 22 in the end I5 of the sight base. The hood I! is thus securely held upon the sight base,

but can be removed at will merely by retracting the collar is an amount suflicient to enable the tube to be drawn rearwardly to clear the groove 2|.

It will be understood that the invention is readily susceptible to other embodiments, all falling within the scope of the appended claims:

What is claimed is:

1. In a. firearms sight comprising an upstanding sight base and a cylindrical hood, means for securing said hood to said-base comprising an arcuate groove in said base, there being an aperture in said hood adapted to receive said base, a collar threaded on said hood and adapted to be advanced to cover a portion of said aperture, a second arcuate groove in said base adapted to receive the end portion of said collar when so advanced, the construction and arrangement being such that by advancing the collar a portion of the edge of said aperture is drawn into said first-mentioned arcuate groove and the end portion of the collar is engaged in said second arcuate groove to firmly secure said hood to said base.

2. In a firearms sight comprising an upstanding sight base and a hood, means for securing said hood upon said base comprising an aperture in said hood substantially conforming in size and shape to said sight base, there being a recess in said base adapted to receive a portion of an edge of the aperture in said hood, a collar threaded to said hood, and a second recess in said base opposed to said first recess adapted to receive a portion of said collar to lock said edge in its recess.

3. A firearms sight comprising a cylindrical hood and a sight base provided with a generally rectangular upstanding sight support, said hood having an aperture therein substantially conforming to a transverse section of said sight support and thereby fitting on said sight support, there being a groove in one side of said sight support adapted to receive an edge of said aperture, there being a second groove in said sight support, and a member adjustably mounted on said hood adapted to be advanced into said second groove when the hood is in place on the support, thereby causing the first mentioned edge to engage the first mentioned groove and looking said hood on said sight support.
